Abstract

<P>PROBLEM TO BE SOLVED: To prevent trouble in reproduction order management of musical compositions caused by rewrite of a file name by a user in a digital audio player by storing the name of a music file in a built-in hard disk so as to be usable for reproduction order management of musical compositions or display management of musical composition names or the like. <P>SOLUTION: The main body of the name assigned to a music file within the built-in hard disk is divided, except the extender thereof, to a head-side section and a terminal-side section. The head-side section includes a numerical value related to serial number. The terminal-side section includes a text for musical composition information. The terminal-side section of the file name is allowed to be changed by the user, but the head-side section of the file name is prohibited from being changed by the user. Since the head-side section is maintained even if the file name is changed by the user, reproduction of a plurality of reproduction files is performed in a correct reproduction order. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a file management apparatus, a file management method, and a program for managing a reproduction file such as a music file in a storage device, and more particularly to a file management apparatus, a file management method, and a program that use a file name for managing the reproduction file. It is.

  In audio editing software installed in a PC (personal computer), when a music file for a CD-DA (Compact Disc Digital Audio) music is generated in a storage device such as a PC HD (hard disk) by ripping, for example, , "Half-width space-Half-width space ("-")" is used as a delimiter to divide the file name into multiple categories, and "" Track number "-" Artist name "-" Music name "-" Album name " The file name in which music information is entered in each category is given to each music file. Then, when the predetermined album is reproduced later, the information of each division of the file name is used as the reproduction order and display information.

  Note that the artist name and the song name were obtained from CD text or a CDDB (CD database) server such as the Internet, and the CD-DA to be ripped this time does not have CD text, When there is no corresponding music information in the CDDB or when the CDDB cannot be used, the file name correspondence classification is null, and the user manually inputs the music information later.

Patent Document 1 discloses CD ripping (paragraph 0002 of Patent Document 1), and in the case of ripping, when album information is not registered in the CDDB for the data source CD-DA, instead of the song name or the like. Appropriate values such as serial numbers are used as tag information of the audio file (paragraphs 0004 and 0027 of Patent Document 1), and the user can rewrite the tag information later on these audio files (Patent Document) 1 paragraphs 0032, 0034 and FIG. 5) are disclosed.
JP 2004-246937 A

  In some cases, a user manually inputs a music file that includes information on the serial number and music name in the file name, and the audio device itself automatically changes the file name. In the conventional audio device, there is no restriction on the change of the file name. Therefore, for example, if the serial number or separator in the file name is changed, the songs in the album cannot be played in the correct order when the album is played after the file name is changed.

  Tag information for storing serial numbers, album names, etc. in Patent Document 1 is not included in the file name, but is stored in the file together with the audio data (see Paragraph 0019 of FIG. 3 and FIG. 3b1, FIG. 3). b2). In addition, in the audio of Patent Document 1, the serial number assigned first as tag information is temporarily recorded, and is overwritten by the album name or the like by the user later and disappears (see FIG. 4 of Patent Document 1). Steps 432 and 434) are not used as management data for the reproduction order during reproduction.

  An object of the present invention is to provide a file management apparatus, a file management method, and a program that use a file name for predetermined management of a playback file in a storage device, and the file name can be changed by a user or the like without causing any trouble in the management. Is to guarantee.

  According to the file management apparatus of the present invention, the file name is divided into a plurality of file name components, each file name component is assigned to a different management system, and the file name portion of each file name component is Used as management data for the management system. For the file name configuration unit assigned to the system in which the change of the file name part interferes with the management, the change of the file name part is restricted. For a file name component assigned to a system in which the change of the file name part does not interfere with the management, the change of the file name part is allowed.

  A file management apparatus according to the present invention includes: a reproduction file recording unit that records a reproduction file for reproducing content information; and a file name assigning unit that assigns a file name to the reproduction file recorded by the reproduction file recording unit. Have. The file name is composed of a combination of a first file name component and a second file name component. The file name portion of the first file name component is restricted from being changed, and the file name portion of the second file name component is allowed to be changed.

The file management method of the present invention
Recording a reproduction file for reproducing content information in a storage device;
The file name of each playback file recorded in the storage device is divided into first and second file name components, continuous description is given to the first file name component, and the second file name The component is provided with a description associated with the attribute of the playback file;
In changing the file name, the file name portion of the first file name component restricts the change, and the file name portion of the second file name component permits the change;
have.

  The program of the present invention causes a computer to function as each means of the file management apparatus of the present invention.

  According to the present invention, the file name is divided into first and second file name components, and the file name portions of the first and second file name components are restricted and allowed to be changed, respectively. As a result, it is possible to ensure a change related to the file name by the user or the like while avoiding troubles in predetermined management.

  FIG. 1 shows various apparatuses that implement file name management software for AV (Audio & Visual) files and their linkages. The AV file includes an audio file such as MP3 standard and WAV standard, an image file such as JPEG standard, and a moving image file such as MPEG standard. Hereinafter, for simplicity of explanation, the AV file is assumed to be a music file which is a kind of audio file.

  The digital audio player 10, the stationary audio device 11, and the PC 12 as playback devices incorporate a storage device such as a hard disk or a flash memory, and store music files in the storage device. The digital audio player 10, the stationary audio device 11 and the PC 12 appropriately read the music file in the storage device, and can output the music playback sound from its own speaker or earphone, and the music in the storage device. Editing such as changing the file name on the file can be performed as appropriate by the device itself.

  The stationary audio device 11 and the PC 12 copy or move the music file stored in the hard disk device of the device to a removable flash memory such as an SD memory card, and the removable flash memory is transferred to the digital audio player 10. It is also possible to play the music in the removable flash memory with the digital audio player 10 attached. Further, the music file in the detachable flash memory can be edited by the stationary audio apparatus 11 and the PC 12 such as a file name.

  The digital audio player 10 and the stationary audio device 11 are connected to each other via a cable 15. In the connection state with the cable 15, the music file in the storage device of the stationary audio device 11 is encrypted and then stored in the storage device of the digital audio player 10, or the music file in the storage device of the digital audio player 10 is stored by the user. Can be edited in the stationary audio device 11, and the user can output the music playback sound of the music file in the storage device of the digital audio player 10 from the speaker of the stationary audio device 11.

  Similarly, the digital audio player 10 and the PC 12 are connected to each other via a cable 16 such as a USB cable. When the cable 16 is connected, the music file in the storage device of the PC 12 is encrypted and then stored in the storage device of the digital audio player 10, or the user edits the music file in the storage device of the digital audio player 10 on the PC 12. It is possible to do.

  Similarly, the stationary audio apparatus 11 and the PC 12 are connected to each other via a cable 17 such as a USB cable. In the connection state by the cable 17, the music file can be transferred between the stationary audio device 11 and the PC 12, or the user can edit the music file in the storage device of the stationary audio device 11 on the PC 12. It is.

  FIG. 2 shows a process of changing a file name when a CD-DA music without CD text is ripped and a name editing operation is subsequently performed by the user. The ripping from the CD-DA may be performed in any of the digital audio player 10, the stationary audio apparatus 11, and the PC 12, but hereinafter, for convenience of explanation, the digital audio player 10 is selected as a representative. The case of the digital audio player 10 will be described. In the digital audio player 10, files in the storage device are managed in a tree structure.

  As an assumption for convenience of explanation, as shown in FIG. 2A, there is one folder with the name “ABCD” in the storage device before ripping, and ABC. mp3, efg. wma, HIJ. Assume that three files of doc are stored. Regarding the extension of the file name, mp3 indicates that the file is an audio MP3 standard file, wma indicates that the file is an audio wma (Windows Media Audio) standard file, and doc is a word processor software of Microsoft Corporation. It is a Word file.

  With the ripping of the CD-DA music, the folder with the folder name “Album001” is located under the folder with the folder name “Special” in the storage device of the digital audio player 10 as shown in FIG. Created as a hierarchy. The folder name “Album001” is a folder name that the digital audio player 10 gives as a default folder name when ripping from a CD-DA. If the current CD-DA has CD text, the folder name “Album001” is typical. Is the album name of the CD-DA album instead of “Album001”. Note that the folder with the folder name “Special” is set as a special folder in the storage device in the digital audio player 10, and the digital audio player 10 instructs the editing request and playback request related to the music file from the user. Then, first, the folder “Special” is accessed, and the corresponding music file is searched from the folder.

  An example of a file name assignment standard that can be adopted in the digital audio player 10 will be described. With regard to the file name, the part excluding the extension is called a main body, and the file name is divided into two sections, that is, a head side section and a tail side section in the main body. As a fixed-length file name assignment standard, for example, the head segment can be defined as a range of 1 to 8 bytes of the file name body, and the tail segment can be defined as a range after 9 bytes. In the variable length file name assignment standard, for example, a predetermined delimiter (for example, “-”) is set, and in the main body of the file name, the front side segment and the end side segment are before and after the delimiter, respectively. May be identified.

  In this example, each piece of music data in the folder is converted into a wma standard music file and stored in the folder “Album001”. Each music file has a file name: TR001-null. wma, TR002-null. wma,... are assigned. With “−” as the boundary, the section before the boundary is the head side section and the rear is the tail section.

  In the example of FIG. 2 and FIG. 3 to be described later, the head side section of the file name is a file name portion including numerical values relating to the track order in the CD-DA. Further, “null” in the end side classification of the file name is used not to indicate the character itself but to mean empty. In the digital audio player 10, the numerical value included in the head side section is used for management of the reproduction order as management data for the serial number. Further, at the stage of FIG. 2B, the end side section of each music file is null (empty).

  Ripping based on CD-DA without CD text ends in the file name state of FIG. When the digital audio player 10 receives a user instruction for all-track playback or continuous playback for the folder “Album001”, the digital audio player 10 detects a numerical value related to the serial number included in the head side classification of the file names of the music files in the folder, and The music of each music file is played in order. During the playback of each music file, text information such as the music name of the playback music is displayed on the display of the digital audio player 10 based on the file name portion of the end-side section. Since this is null in the state of FIG. 2 (b), this digital audio player 10 cannot display the information related to the file name portion of the end side section and either does not display or instead, The file name part of the head side section is displayed on the display.

  After ripping, the user edits the file name himself / herself in order to display appropriate music information on the display during reproduction of the music of each music file. In addition, by connecting the digital audio player 10 to a CDDB server via the Internet and downloading music information from the CDDB, the digital audio player 10 can be automatically input instead of the user input. The editing of the file name by the user is prohibited for the first section of the file name, and only the last section is targeted. FIG. 2C shows a state in which the user has changed the file names of the music files 1 to 3 in the folder “Album001”.

  In FIG. 2 (c), the music files with serial numbers 1 to 3 are left unchanged in the head section, but are changed in the tail section, and the file names are “TR001-kakikukeko.wma”, respectively. "," TR002-susesisso.wma "," TR003-tittituto.wma ". Even after the file name is changed, when the user instruction for all-track playback or continuous playback is received for the folder “Album001”, the digital audio player 10 receives the numerical value included in the head side section of the name of each song file in the folder. Thus, it is possible to determine the turn number of each file and to reproduce the music of each music file without any trouble in the order of the turn. In addition, when the music numbers 1 to 3 are played back, the display of the digital audio player 10 displays “kakikukeko”, “sasisuseso”, and “tattitute” in the end of the file name as playback music information, respectively. become.

  “Kakikukeko” or the like of the end section of each music file input by the user is typically input in a predetermined order while separating the artist name, music name and album name with a predetermined delimiter for each file. It has become. That is, the file name tail section is further subdivided, and corresponding information is entered for each subdivision. In order to streamline the input operation in the tail section, the delimiter may be automatically input when the user presses the tab key once. When playing back a music file, the digital audio player 10 extracts music information such as a music name and an artist name based on the contents of each sub-section of the end-side section of the file and displays it on the display.

  FIG. 3 shows a process for changing a file name when ripping is performed on a CD-DA with CD text. 3A and 3B are the same as FIGS. 2A and 2B, respectively. In the case of ripping CD-DA without CD text, ripping is completed with the file name state shown in FIG. On the other hand, in the ripping for CD-DA with CD text, the processing is further continued after FIG. 3B, and the digital audio player 10 automatically sets the end side segment of each music file to CD. Edit based on the text and change each file name to the state shown in FIG.

  In FIG. 3 (c), the end side division of each music file is “TR001-kakikukeko.wma”, “TR002-susesisso.wma”, “TR003-tattituto.wma”. “TR004-naninuno.wma”, “TR005-hahihuheho.wma”. Since the digital audio player 10 automatically inputs the end classification of the file name based on the CD text of the CD-DA, the time-consuming manual input in FIG. 2C is omitted.

  FIG. 4 shows the internal memory 23 in the file name rename together with the pointer 24. FIG. 4A shows the contents of the internal memory 23 at the start of editing, and FIG. 4B shows the contents of the internal memory 23 when only four characters have been entered. In the state of FIG. 4, the internal memory 23 is not in the overwrite mode but in the insertion mode.

  The file name is renamed automatically by the digital audio player 10 or by the user. The rename from FIG. 2B to FIG. 2C is an example performed by the user, and the rename from FIG. 3B to FIG. 3C is automatically performed by the digital audio player 10. It is an example. The renamed file name data is stored in the internal memory 23, and the name of the corresponding file in the storage device of the digital audio player 10 is changed based on the data in the internal memory 23 as soon as the rename is confirmed.

  As the renaming of the file name starts, the data of the file name to be renamed is read from the storage device of the digital audio player 10 and inserted into the internal memory 23. In the example of FIG. 4, it is assumed that the file name “TR001-null.wma” of the folder “Album001” is the object to be renamed in the storage state of FIG. 2B or 3B. In the internal memory 23, TR001. wma bytecode is inserted.

  The pointer 24 is controlled by predetermined cursor control means (not shown) so that the next input character indicates the character digit to be input to the internal memory 23. The pointer 24 shifts in the left-right direction in units of one character digit (one byte), and skips the character digits that are prohibited from being input among the character digits in the internal memory 23. Note that double-byte characters are 2 bytes, and the pointer 24 moves by 2 bytes each time double-byte characters are input or deleted. The input-prohibited character digits are fixed in the fixed-length file name assignment standard for the start and end divisions, but in the variable-length file name assignment standard, it is based on the position of the delimiter in the file name. Change each time. You may enable it to adjust the character digit of a delimiter character position suitably by a user setting.

  As described above, since the renaming of the first section of the file name is prohibited, the pointer 24 points to “.” In the seventh digit in FIG. As a result, the rename of the head section is not changed. If it is assumed that the user has input up to “kaki” in the file name change window 29 (FIG. 5), which will be described later, and the finalized input operation has been performed, as shown in FIG. “Kaki” is sequentially input to the memory 23, and the pointer 24 moves to the right by one character digit together with “.wma” to indicate “.” In the eleventh digit. In the digital audio player 10, renaming is prohibited even after the period that separates the main body of the file name from the extension. Thus, only the tail section of the file name body is changed.

  In FIG. 2C and FIG. 3C, the change of the file name end side segment does not end with “kaki”, after which “kukeko” is additionally input, and the file name end segment is set to null. It is shown that it was finally changed to “kakikuko”. In this case, the character digit pointed to by the pointer 24 in FIG. 4 is the character digit “.” Next to “ko”.

  5 and 6 show an entire display method file name change window 29 and a partial display method file name change window 33 which are displayed on the display of the digital audio player 10 when the user renames the file name. That is, in the file name change window 29 of FIG. 5, not only the end side division of the file name but also the entire file name is displayed including the head side division and extension where the renaming is restricted. In the file name change window 33 of No. 6, only the end-side division that is allowed to be renamed is displayed without displaying the start-side division and the extension. In both the file name change windows 29 and 33, it is assumed that the user input is not the overwrite mode but the insertion mode.

  There is a predetermined buffer (not shown) corresponding to the file name change windows 29 and 33, and characters inputted by the user from the character key are stored in the buffer one by one and stored in the buffer. Characters are displayed in the file name change windows 29 and 33. In the initial stage, the buffer stores the same data as the internal memory 23 of FIG. In the case of the file name change window 29 in FIG. 5, characters corresponding to all character data in the buffer are displayed in the file name change window 29, whereas in the case of the file name change window 33 in FIG. In the file name change window 33, only the character data of the end side division related to the file name change allowable file name portion of all the character data in the buffer is displayed.

  5 (a) and 6 (a) correspond to FIG. 4 (a). The cursor 30 indicates a character digit to be input next by the user in the file name change windows 29 and 33. The pointer character (FIG. 4) and the cursor 30 (FIGS. 5 and 6) match the character string of the pointer 24 (FIG. 4) and the cursor 30 (FIGS. After the user inputs characters in the file name change windows 29 and 33, the characters before the pointer 24 (FIG. 4) and the cursor 30 (FIGS. 5 and 6) deviate before the input characters are confirmed.

  In FIG. 5A, the cursor 30 indicates “.” As the first character digit of the end side section of the file name as the file name portion that is allowed to be changed. In FIG. 6A, no characters are displayed in the file name change window 33 because of null, but the cursor 30 indicates the first character digit of the display character string.

  FIG. 5B and FIG. 6B show a state in which the user has input to the file name change windows 29 and 33 up to “kaki” in the current input character string “kakikukeko”. As the character input progresses to the file name change windows 29 and 33, the cursor 30 moves to the right by one character digit.

  Since it is the insertion mode, in the case of the file name change window 29, “wma” moves as “.” Moves. In the case of the file name change window 29, it is prohibited to change “.wma” even in the overwrite mode, and the cursor is in any character of “.wma” as the change restricted file name portion. The location is not indicated.

  If the user operates the enter key in the character input state of FIGS. 5B and 6B, the data in the buffer is copied to the internal memory 23 (FIG. 4), and the contents of the internal memory 23 are as shown in FIG. It becomes what is shown in b).

  As the user uses the music file in the digital audio player 10, the user may delete unnecessary music files from the storage device. 2 and 3, the name portion related to the serial number is a three-digit number such as 001, 002,... Can only be allocated. The serial number of the deleted music file becomes a missing number, and when such a number increases, the number of music files in the storage device is within the maximum number of 999, and the number of music files in the back is changed. You will not be able to assign a serial number.

  In order to cope with this, in the digital audio player 10, when the last serial number is close to the maximum value, the serial number is appropriately reassigned (also referred to as “refresh”) based on a user instruction or automatically. It is like that. Naturally, during the renumbering processing period, the restriction on changing the first division of the file name is released. Then, with respect to the files remaining in the storage device, the sequential number portion of the head side section of each music file is changed so that the sequential number order is maintained and the sequential number is continuous. As a result, the missing serial number is eliminated.

  Also for folders, the folder name can be divided into a head side section and a tail side section, and restrictions and allowances can be taken for changing the folder name portion of the head side section and the tail side section, respectively. For example, a name including a numerical value related to the serial number is assigned to the first section of the folder name, and a name including an album name or an artist name is assigned to the last section of the folder name. The portion of the head side division of the folder name is maintained despite the change of the folder name by the user, so that the reproduction order of the folders can be maintained when reproducing a plurality of folders at once.

  FIG. 7 is a flowchart of the ripping process. The ripping process corresponds to the file name changing process shown in FIG. 2 (a) → FIG. 2 (b) and FIG. 3 (a) → FIG. 3 (b) → FIG. In S35, a file name including a numerical value related to the serial number is assigned to each music file. In S35, Tr01, Tr02,... Indicate the track number of each song in the CD-DA, and TR001-null. wma, TR002-null. wma,... indicate file names.

  In S36, it is determined whether or not the CD text copy function in the digital audio player 10 is ON. The user can select ON / OFF of the CD text copy function. If the determination in S36 is positive, the process proceeds to S37, and if not, the ripping process is terminated.

  In S37, it is determined whether or not the current CD-DA has CD text. If the CD-DA is positive, the process proceeds to S38, and if not, the ripping process is terminated. In S38, in the file name of each music file, a file name part including the corresponding CD text is added after the file name part related to the serial number, that is, in the end side section.

  FIG. 8 is a flowchart of the file name change process. In addition to FIG. 2 (b) → FIG. 2 (c) and FIG. 3 (b) → FIG. 3 (c), the file name changing process includes files belonging to the folder “ABCD” in FIG. 2 and FIG. .Doc) also applies to renaming.

  In S41, it is determined whether or not the numerical value portion related to the serial number is included in the file name to be changed. If the determination is positive, the process proceeds to S42, and if not, the process proceeds to S43.

  In S42, the position of the pointer 24 in the internal memory 23 (FIG. 4) is set next to the head side section of the file name, that is, at the head of the tail side section. In S43, the position of the pointer 24 in the internal memory 23 is set to the head of the file name.

  In S44, the file name is changed. The change of the file name is not performed on the character digits that are restricted by the control by the pointer 24 in the internal memory 23 (for example, the head side division of the file name), and the character digits that are allowed to be changed (example: : Only at the end of the file name). Therefore, the file name that includes the numerical value related to the serial number in the first section, the numerical value of the first section is not changed in spite of the file name change. The playback order of the music is retained.

  FIG. 9 is a block diagram of the file management apparatus 50. The digital audio player 10, the stationary audio device 11, and the PC 12 in FIG. 1 are specific examples of the file management device 50. The processing of the file management apparatus 50 includes the processing described with reference to FIGS.

  The file management device 50 includes a reproduction file recording unit 51 and a file name assigning unit 52. The reproduction file recording means 51 records a reproduction file 58 for reproducing the content information in the storage device 59. The file name assigning unit 52 assigns a file name to the reproduction file 58 recorded by the reproduction file recording unit 51.

  The file name is composed of a combination of a first file name component and a second file name component. The file name portion of the first file name component is restricted from being changed, and the file name portion of the second file name component is allowed to be changed.

  Specific examples of the first and second file name components are the above-mentioned head side section and tail side section in the file name body. A plurality of first and second file name configuration units may be set for each reproduction file instead of one each. In addition, the second file name configuration unit may come closer to the head than the first file name configuration unit.

  The reproduction file 58 includes at least a music file, an image file, and a moving image file. In the second file name configuration unit, the description associated with the attribute of the playback file 58 is, for example, a song name, album name, or artist name included in the CD text. When the user wants to attach his own memo to each playback file 58, the second file name can be used.

  Regardless of the change of the file name, the change of the file name portion of the first file name component is restricted, and as a result, the trouble of managing the playback file using the file name portion of the first file name component is eliminated. Is done. In addition, by allowing the change of the file name portion of the second file name configuration unit, the file name can be changed, and the user can give favorite information to the file name.

  The preferred file management device 50 further includes file name display means 53 and cursor display means 54. The file name display means 53 displays the file name on the display device 60 for performing a file name operation by the user. When the file name displayed by the file name display unit 53 is changed, the cursor display unit 54 displays a cursor indicating the input character position in the file name. The cursor display means 54 instructs the cursor only to the second file name component.

  The user can know the range of the input restriction in the file name by looking at the cursor in the file name in the display device 60, and can know where in the file name the next input character is input. .

  For example, the file name display means 53 does not display the file name portion of the first file name component, and displays the file name portion of the second file name component. As a result, the file name portion whose change is restricted is hidden from the display device 60, so that the user can efficiently edit the file name after the change. 5 and 6 described above are examples in which the file name display means 53 displays the entire file name on the display device 60, and among the file names, the file name of the second file name component to which the change is provided. This is an example of displaying only a part.

  Typically, a file name portion including a continuous description among a plurality of files is given to the first file name configuration unit. The continuous description in the first file name component includes, for example, continuous numerical values (example: 001, 002, 003,...), Continuous characters (example 1: a, b, c,...). Example 2: A, i, u,..., And a mixture thereof (example: a01, a02,..., A99, b01, b02,... B99, c01,...).

  Preferably, such continuous description is a description relating to a predetermined processing order for a plurality of playback files 58. The predetermined processing order is, for example, the default ripping order when the user does not designate the ripping order when ripping from the CD-DA, that is, the track number order in the CD-DA, or the user designates the ripping order. And the recording order of the playback file 58 in the storage device 59 (the recording order is usually the same as the ripping order).

  The file name portion of the first file name configuration unit is used as sort management data for a plurality of playback files 58, for example. As the sort management data, there is, for example, a serial number that defines the playback order of music.

  The second file name configuration unit is, for example, text data of content information of the reproduction file 58. Specific examples of such text data include a song name, artist name, and album name included in the CD text. Furthermore, a memo of content by the user may be included in the second file name configuration unit.

  The user may delete unnecessary reproduction files 58 as appropriate. Accordingly, at the beginning of the ripping, the file name portion of the first file name component is discontinuous partially missing although the description is continuous. In addition, due to restrictions on the number of characters for the first file name component, there is a maximum value for continuous description, and the first file name assigned to the playback file 58 may be exhausted.

  To cope with this, the file name portion of the first file name component part is resolved in order to eliminate the discontinuity at the time when the lack of continuous description becomes appropriate for the first file name component part of the file name. It is desirable to re-assign. Preferably, the file name assigning unit 52 removes the restriction on the change of the first file name component for a part of the continuous file name portion missing in the first file name component between a plurality of playback files. Then, a continuous file name portion is reassigned to the first file name component of the plurality of files. Note that the serial number or the like may be set independently for each folder in the storage device 59, or a continuous serial number may be set for the entire storage device 59.

  The file name assigning means 52 may be applied as a means for assigning a folder name to a folder including at least one playback file 58 instead of giving a file name to the playback file 58.

  The file management method 70 is demonstrated based on the flowchart of FIG.10 and FIG.11. FIG. 10 is a flowchart of a file name recording routine in the file management method 70, and FIG. 11 is a flowchart of a file name change routine in the file management method 70. The file name recording routine (FIG. 10) is activated when a new reproduction file 58 is recorded in the storage device 59, for example, at the time of ripping.

  The file name change routine (FIG. 11), for example, when ripping from CD-DA with CD text, includes when CD text is included in the file name, or when the user renames the file name after ripping. to start. The process of FIG. 2 (b) → FIG. 2 (c) is an example of the latter, and FIG. 3 (b) → FIG. 3 (c) is an example of the former.

  In the reproduction file recording routine (FIG. 10), in S71, a reproduction file 58 for reproducing the content information is recorded in the storage device 59. In S72, the file name of each playback file 58 recorded in the storage device 59 is divided into first and second file name components, continuous description is given to the first file name component, and A description associated with the attribute of the reproduction file 58 is given to the second file name component.

  In the file name change routine (FIG. 11), in changing the file name, the file name portion of the first file name component is restricted from being changed, and the file name portion of the second file name component is allowed to be changed.

  That is, in S76, it is determined whether or not the current file name change is for the file name portion of the first file name component. If the determination is positive, the process proceeds to S77. Proceed to S78. In S77, the change of the file name portion of the first file name component is restricted. The restriction on the change of the file name portion is, for example, prohibition of the change. The file name portion of the first file name component may not be fully changed, but may be changed partially to allow changes other than the continuous description such as serial number.

  In S78, it is determined whether or not the current file name change is for the file name portion of the second file name component. If the determination is positive, the process proceeds to S79. Exit. In S79, the second file name is allowed to be changed.
